DI Assignment of LSP group selection

The LSP group selection can be set for internal contacts 1 to 3 using the DI
Assignment.

• Details of LSP group selection with the internal contact function

The following shows the LSP group selection value according to the ON/OFF
status of each internal contact:

LSP group selection (0/+1)

OFF: 0

ON: 1

LSP group selection (0/+2)

OFF: 0

ON: 2

LSP group selection (0/+4)

OFF: 0

ON: 4

The value, that "1" is added to the sum of the LSP group selection values
according to the ON/OFF status of each internal contact, becomes the LSP group
number.
For example, when the sum of LSP group selection values of internal contact 1 to
3 is "1", the LSP group number becomes "2".

• Even though the LSP system group is "1", the display and setting can be made,

but the LSP group selection with the internal contact function becomes invalid.

SP ramp unit

The unit of the SP up/down ramp can be set.

• "0.1U" shows that the decimal point position of the PV is shifted one digit

rightward.

Example: When the thermocouple input is in a range of -200 to +1200˚C, "0.1U"

is "0.1˚C ".

Example: When the DC voltage input is in a range of 0.0 to 100.0, "0.1U" is

"0.01".

Handling Precautions

When using the DC voltage/DC current input with setting of 3 digits

after the decimal point, "0.1U" is "0.0001".

However, the SP up ramp/SP down ramp setting cannot display 4

digits after the decimal point, the value is displayed without use of the

decimal point.
